Common know-how of the XFINITY Internet speed test

Why is the upload and download speed for XFINITY internet connection different?

XFINITY is an internet service provider that has a limited bandwidth as per the internet plan is chosen by the users. The upload speed of the XFINITY speed tests is often lower than the download speed.

This is because like all the other internet service providers XFINITY also tends to prioritize the download speeds over the upload speeds for the users as people are more into downloads than in uploading the content.

To understand this using an example, while using Netflix to stream a film, major data transmission takes place from Netflix’s server to your home network i.e. download takes place and the upload part involves only the small request placed while the user interacts with the Netflix interface such as pushing pause, fast forward, selecting film, etc.

Is the Latency of XFINITY Normal?

Our XFINITY speed test tool also measures latency along with the download and upload speed. Latency refers to the measure of the time that the data takes for traveling from home network to the server and then come back to the server. It is measured in milliseconds (ms) also it can be taken as the measurement of the “lag”.

Latency is of greater value especially for video chat, gaming, and other online activities. However, latency is never a concern while you scroll through Facebook or perform any other online activities.

The latency measure as per the records of XFINITY speed test provides the results similar to other internet service providers and is widely accepted for the vast majority of users no issue in the performance due to latency.

Why you should perform XFINITY speed test with

It is usually a conflict of interest while internet service providers have their own speed tests and hence a third party opinion is always required.

There may be a possibility that the internet providers eliminate the variables that you need to test in their internet speed tests or may remove the routing factors that makes the connection appear faster even if it is not.

However, testing the speed with the third party ensures you that whether your service provider is reliable and is not overcharging you. XFINITY speed test with is absolutely free and unbiased providing almost accurate results.

What is good download speed?

GWhat is a good internet speed? A good internet speed is at or above 25 Mbps. These speeds will support most online activity, such as HD streaming, online gaming, web browsing and downloading music.

What is good upload speed?

Upload speeds of 10 Mbps or higher are generally considered fast internet speeds for upload because they can easily handle the common activities of the average user. For example, Skype recommends upload speeds of 1.2 Mbps or higher for HD video calling

What is a good internet speed?

Usually, the internet speed ranging from 4-6Mbps often provides a good surfing experience and is generally faster enough to stream high definition 720p video. This speed range ideally allows you to download few videos within about 20 minutes and a speed below this i.e. 4Mbps can still be too slow.

However, good internet speed is hard to decide as it varies from person to person and the kind of usage. For those working from home and watching, videos, streaming Netflix, etc. potentially require much higher internet speeds.

How can I test my WiFi Speed or Wireless speed?

While most of the internet service providers provide their own wifi speed test tool, but to get more reliable, unbiased and accurate internet speed results you shall opt for a third party wireless speed test. is one of the widely used platforms for XFINITY internet speed test.

Why is my internet so slow?

There are many reasons your Internet connection might appear slow. It could be a problem with your modem or router, Wi-Fi signal, signal strength on your cable line, devices on your network saturating your bandwidth, or even a slow DNS server

If your speed test still gives the result saying that your internet connection is slow then try to reboot your router or device and make sure that there is no Quality of service i.e. QoS features turned on into your router.

If you still face the problem try the other troubleshooting methods like resetting the router, customizing the configuration settings and more. If none of the methods are successful, then contact your Internet Service Provider and ask him to diagnose the problem.

Why do I get different internet speeds on my computer and my phone/tablet?

Your internet speed heavily depends on your network equipment, such as the router or cable). For example, an ethernet connection is generally more stable and quicker than Wi-Fi. If you're using a Wi-Fi connection, your internet speed might decrease as more devices connect to the same network.

In case you obtain different results for your network connection then ensure that:

  • You test the same connection i.e. all your devices on which you perform internet speed test are connected to the same network.
  • You test the same server. selects the server automatically for testing on the basis of ping. However, you can also select the server to do so.

Additionally, there exists a large difference in both cellular radio quality, WiFi and MIMO stream handling quality amongst the devices. Such variations might enable the device to give slower test results in comparison to other computer or device.

What’s an acceptable latency or ping for gaming online?

Here it is complete details:

  • Winning: 0-59 ms
  • In the game: 60-129 ms
  • Struggling: 130-199 ms
  • Game over: 200+ ms

What does changing the testinternetspeed server do?

Our app relies on network of more than 1,000 host servers that are operated and owned by various internet service providers (ISPs) as well as the mobile carriers across the globe.

By default, Our application chooses the nearby server that has a faster ping result, in order to reach the maximum potential of your internet connection.

Testing to the sponsored servers does to give the actual speed of your connection and does not necessarily let you know how fast is your internet connection if you sign up for the sponsor’s services.

What means server not found?

The “Server Not Found” error usually means that your domain (DNS) is not pointed correctly to us. What you need to do is resolve the domain name to the server here. To do so, check our How to check my DNS (nameservers) and point my domain name?


Download speed is a measure of how quickly your computer can download information from somewhere else, measured in Mbps. This is usually the most important measurement in a speed test because it lets you know how fast you can download large files or how well you can stream high-quality video. Having a high download speed can impact the quality of your Netflix stream (especially if you want to watch in 4K resolution) or how quickly you can download the latest game to your PlayStation 4 console. Higher numbers are better here.

  • The client establishes multiple connections with the server over port: 8080. The client requests the server to send an initial chunk of data.
  • The client calculates the real-time speed of the transfers, then adjusts the chunk size and buffer size based on this calculation to maximize usage of the network connection.
  • As the chunks are received by the client, the client will request more chunks throughout the duration of the test.
  • During the first half of the test, the client will establish extra connections to the server if it determines additional threads are required to more accurately measure the download speed.
  • The test ends once the configured amount of time has been reached.


This is the opposite of download speed, measured in the same way. Upload speeds are especially important for sharing video files, so budding YouTube stars and videographers should consider plans promising high upload speeds. The higher your upload speed, the faster you can send information to other places or upload files to a server.

  • The client establishes multiple connections with the server over the defined port and sends an initial chunk of data.
  • The client calculates the real-time speed of the transfers and adjusts the chunk size and buffer size based on it to maximize usage of the network connection, and requests more data.
  • As the chunks are received by the server, the client will send more chunks throughout the duration of the test.
  • During the first half of the test, the client will establish extra connections to the server if it determines additional threads are required to more accurately measure the upload speed.
  • The test ends once the configured amount of time has been reached.


Ping is a computer network administration software utility used to test the reachability of a host on an Internet Protocol network. It is available for virtually all operating systems that have networking capability, including most embedded network administration software. It is measured in milliseconds (ms).

Packet loss

Packet loss might occur while sending a packet of data over the internet and it is not received or is still incomplete. Packet loss is defined in terms of percentage of lost packets as compared to the data packets sent. Packet loss in majority of the cases is a result of weak line/signal quality.


Jitter internet is a measure of how stable your connection is. The speed test will run ping measurements several times, with the jitter recording how much variation there is. Low jitter means your connection is stable; high jitter indicates that there might be a bigger issue with your connection. Jitter is generally higher on mobile connections.


Mbps or Megabits per second is a standard unit of measurement of the internet speed. One Megabit is equivalent to one million bits of information. Mbps shouldn’t be confused with MB i.e. Megabytes, which is the measure of the size and not the bandwidth.


Kbps or Kilobits per second is a standard unit of measurement for internet speed particularly the slower connections. A kilobit is equivalent to 1,000 bits of information.

Shouldn’t be confused with kilobytes (KB) as it is a measure of the size and not bandwidth.
